My b20b's intake manifold(the so called "giraffe) is of course way to tall for the hood, so Im in the search for one. A few questions if u will: this is for a '97 b20 Can I use an older LS intake manifold? Can I reuse some of the sensors off the b20's? Will any of the other manifolds(b18c, b16a, etc.) fit on the head?
